Abstract
A flexible back panel for collapsible or folding chairs, the flexible back panel having fastening means so it can be utilized with two different types of folding chairs.
Claims
exact text as granted — not AI-modifiedI claim:
1. A flexible back panel for a folding chair and comprising, a generally rectangular piece of flexible material having a welt defining an upper and lower side of said panel, said panel having opposite, vertical edges, and a first loop and a second loop having open upper ends and forming a pair of loops along each of said opposite edges for the selective reception of a folding chair back post therein, said second loops being located generally concentrically within their respective first loops, said first loops of said pairs of loops being spaced farther apart from one another than the second loops of said pairs of loops, whereby the effective length between the first loops is greater than the length between the second loops.
2. The panel set forth in claim 1 further characterized in that said loops each have welts along their upper and lower sides, and said inner loops are of shorter height than the outer loops whereby the welts nest smoothly therein.
3. A flexible back panel for a folding chair of the type having two spaced apart, upwardly extending back posts, said panel comprising, a generally rectangular piece of flexible material having a welt defining an upper and lower side of said panel, said panel having opposite, vertical edges, and a first loop and a second loop within said first loop and generally concentric therewith and forming a pair of concentric loops along each of said opposite edges for the selective reception of said back posts therein, said first loops of said pairs of loops being spaced farther apart from one another than the second loops of said pairs of loops, said loops having open upper ends for the passage of said posts therethrough to permit the top of said posts to extend upwardly through said loops.
4. The panel set forth in claim 3 further characterized in that said inner loops are of shorter height than the outer loops whereby the welts nest smoothly therein.
5. The panel set forth in claim 3 further characterized in that said posts have an annular notch around their upper end and said welts are adapted to be received in said notches.Join the waitlist — get patent alerts
